Regioregular Poly

Regioregular poly (3-hexylthiophene) was synthesized by exchanging with Grignard agent followed by coupling with catalysis of Ni (dppp)Cl2. A nearly 100% HT-HT structure was verified from 1H-NMR and 13C-NMR data analysis. This highly regioregular structure gives P3HT outstanding stability and certain redshift of absorption spectra was found in contrast to materials with lower regioregularity.

Synthesis And Characterization

This study is concerned with the synthesis and characterization of 4-thiazolidinone derivatives (3a-3e). These compounds were prepared by reacting mercaptoacetic acid with the appropriate Schiff bases (imines) by heating at 50-60 °C in chloroform with moderate yields (51- 75 %). The structures of these 4-thiazolidinone derivatives were established on the basis of spectral studies using IR, 1H-NMR, 13C-NMR, and13C-NMR DEPT .

Synthesis And Characterization

The synthesis of thiacalix[3]triazines and 1,3,5- tris(4-bromophenyl)benzene have been synthesized via simple steps and was characterized to determine the chemical structure. The structure of Thiacalix[3]triazines was characterized via 1H NMR and 13C NMR that conformed the expected structure of compound. In addition, the thiacalix[3]triazines exhibited the λmax at 560 nm and λonset at 720 nm which corresponding to the bandgap of 1.7 ev. Thiacalix[3]triazines, cyclotrimeric metacyclophanes with direct S linkages between the heteroaryl constituents, were shown to associate with anion that could be useful for chemsensor application.

Ethyl Methyl Ketone

To obtain biologically active compounds, the synthesis of some new derivatives with an o-hydroxybenzamide structure was performed. The ethyl esters 4-6 were obtained by the reaction of 5-chloro-2-hydroxy-N-phenylbenzamide and chloro-substituted acid ethyl esters 1-3 in ethyl methyl ketone. The obtained ethyl esters were condensed with hydrazine yielding the hydrazides 7-8. The hydrazones 11-14 were obtained by the reaction of the hydrazides and the chloro-substituted benzaldehydes 9-10. All the newly synthesized compounds were characterized by FTIR, 1H-NMR, 13C-NMR, MS and elemental analyses.
